I am 72 also and can see where you are coming from, but if you do not continue doing things you enjoy, what kind of life will you be living? Like so many others said there is no expiration date stamped on us, but we do know it is coming, just do not know when. So live it up, keep your mind and body active. Take care.

P S I have to give myself this pep talk every now and then too.
